* arm: am335x: DXR2: Reset SMSC LAN9303 switch via GPIO upon bootupStefan Roese2014-03-04-0/+10
| | | | | | | | | | | | Since the switch may be re-configured for VLAN usage in Linux (or any other OS), lets reset the switch to its default register values upon power-up. Otherwise network might not be available in U-Boot.

* ARM: AM43xx: Change DDR3 Reset ValueDave Gerlach2014-03-04-1/+1
| | | | | | | | | The bit DDR3_RST_DEF_VAL inside CTRL_DDR_IO represents the default value of the ddr reset value for DDR3 before the EMIF takes over. We must have this bit set high so that on exit from DeepSleep0 within the kernel the reset line has the proper value. Signed-off-by: Dave Gerlach <d-gerlach@ti.com>
* ARM: AM43xx: Write sdram_config to secure_emif_sdram_configDave Gerlach2014-03-04-0/+1
| | | | | | | | | The register secure_emif_sdram_config in control module is copied to the EMIF sdram_config register when it is coming out of DeepSleep0 in order to ensure that the EMIF comes up for the correct type of DDR. Without this, resume can hang from within the kernel. Signed-off-by: Dave Gerlach <d-gerlach@ti.com>
* ARM: AM43xx: EMIF: configure self-refresh entry delayDave Gerlach2014-03-04-2/+2
| | | | | | | | | | Per a suggestion from the hardware team, program the emif_pwr_mgmt_ctrl and emif_pwr_mgmt_ctrl_shdw registers within the EMIF to hold the desired delay in cycles that the EMIF waits without an access to enter self-refresh, in this case 8192 cycles. With this, code desiring to enter self refresh only has to toggle one bit to enable it. Signed-off-by: Dave Gerlach <d-gerlach@ti.com>

| * arm: Switch to -mno-unaligned-access when supported by the compilerTom Rini2014-02-26-138/+248
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we tell the compiler to optimize for ARMv7 (and ARMv6 for that matter) it assumes a default of SCTRL.A being cleared and unaligned accesses being allowed and fast at the hardware level. We set this bit and must pass along -mno-unaligned-access so that the compiler will still breakdown accesses and not trigger a data abort. To better help understand the requirements of the project with respect to unaligned memory access, the Documentation/unaligned-memory-access.txt file has been added as doc/README.unaligned-memory-access.txt and is taken from the v3.14-rc1 tag of the kernel.

It unfortunately has had a impact on size on SPL as well. For example on SDP4430, 32032 bytes before/MLO 35416 bytes after/MLO With this mentioned commit, MLO stops booting on SDP4430 as only 32K is accessible for non-secure (bootloader) s/w on GP devices and the size increase to 56K fails boot. On the latest u-boot commit e7be18225fbea76d1f0034b224f0d1e60f07cfcf, MLO is now at size 35592 bytes, However, I2C is not necessary for SPL to function as we use SR_I2C for controlling the PMIC. Disabling I2C reduces MLO to 32224 bytes which allows OMAP4 GP platform to boot up. Since this is common for all OMAP4 platforms, remove the need for I2C for SPL builds in the common config.

For SD/SPI flash booting way, we introduce the SPL to enable a loader stub. The SPL was loaded by the code from the internal on-chip ROM. The SPL initializes the DDR according to the SPD and loads the final uboot image into DDR, then jump to the DDR to begin execution. For NAND booting way, the nand SPL has size limitation on some board(e.g. P1010RDB), it can not be more than 8KB, we can call it "minimal SPL", So the dynamic DDR driver doesn't fit into this minimum SPL. We added the TPL that is loaded by the the minimal SPL. The TPL initializes the DDR according to the SPD and loads the final uboot image into DDR,then jump to the DDR to begin execution. This patch enabled SPL/TPL for P1010RDB to support starting from NAND/SD/SPI flash with SPL framework and initializing the DDR according to SPD in the SPL/TPL. Because the minimal SPL load the TPL to L2 SRAM and the jump to the L2 SRAM to execute, so the section .resetvec is no longer needed.
